Hi, I’ve just put together the PO Modular 400. I can get sound when I do the first couple of patches in the manual.
The Square, Saw and Sine modules seem to work fine.
Mixer works, LFO works.
I tried doing the patch in https://teenage.engineering/guides/po-modular/400
2.2 A Simple Mono Synth.
The first part is supposed to produce a sound, but doesn’t. I’ve adjusted all the knobs.
I’ve opened the case back up to make sure it was properly connected to the power rail. I changed which port on the power rail it was connected to.
